Description

BACKGROUND

[0001] Portable computer devices are increasingly more common and mobile, such as laptop computers, tablet PCs, ultra-mobile PCs, as well as other mobile data, messaging, and/or communication devices. When a user holds a small, portable device such as a tablet PC or ultra-mobile PC that has an integrated touch-screen, a common interaction technique is to hold the device with one hand and interact with the touch-screen with fingers of the other hand. For example, users can tap-touch targets, user interface elements, or menu items on the touch-screen with a finger. While portable computer devices have become more mobile and convenient, the size of device integrated displays has decreased to accommodate the mobility and convenience of the devices. Many users of portable devices utilize email as a main source of communication and often accumulate hundreds of emails, but can only view a few emails at any one time on a small display. This can make it difficult for a user to scroll or otherwise navigate through many emails, particularly past emails that may have been received in past days, weeks, and/or months.

SUMMARY

[0002] This summary is provided to introduce simplified concepts of a variable rate scrollbar. The simplified concepts are further described below in the Detailed Description. This summary is not intended to identify essential features of the claimed subject matter, nor is it intended for use in determining the scope of the claimed subject matter.

[0003] Embodiments of a variable rate scrollbar are described. In various embodiments, media items, such as email messages, text messages, digital photos, or song selections are grouped by a page, a day, a week, and/or a month that corresponds to a date associated with a media item. A list of the media items is displayed from one of the groups, and the media items that are displayed are selectable from the list. A variable rate scrollbar is displayed and configured for selection to navigate the media items at variable rates according to the groups of the media items.

[0004] In other embodiments, a portable computer device implements a variable rate scrollbar configured for selection to navigate messages that are grouped by a page, a day, a week, and/or a month that corresponds to a date when a message is received. A touch-screen of the portable computer device displays a list of the messages from at least one of the groups. A scrollbar application initiates a display of the variable rate scrollbar to navigate the messages at variable rates according to the groups of the messages. A touch-screen driver can detect an input to the variable rate scrollbar as an individual navigation of the messages when displayed from at least one of the groups, and further, can detect that the input is continued to vary a scrolling rate of the variable rate scrollbar to initiate a display of a different group of the messages.

DETAILED DESCRIPTION

[0010] Embodiments of a variable rate scrollbar provide techniques for a user of a portable device to scroll a display of media items, such as a list of email messages, text messages, digital photos, song selections, or any other type of media items that are listed for user selection. A variable rate scrollbar provides individual navigation of media items, such as email messages, that are displayed and grouped according to any of a page for the current day, a past day, a week, and/or a month. The variable rate scrollbar also provides for variable group navigation to initiate a display of a different grouping of the email messages (e.g., a different past day, a week, or a month). The scrolling rate, or how fast a user can scroll media items, is changed or varied based on how a user can select individual media items, such as in a page view of the email messages, and then jump to select a group of the email messages from a past day, a week, or a month. A user can change the scrolling rate of a variable rate scrollbar without lifting the contact of a touch input on a touch-screen of a portable device. Additionally, when a group of media items is selected, a user can then individually navigate the media items that are associated with the selected group of media items.

[0011] While features and concepts of the described systems and methods for a variable rate scrollbar can be implemented in any number of different environments, systems, and/or various configurations, embodiments of a variable rate scrollbar are described in the context of the following example systems and environments.

[0012] FIG. 1 illustrates an example 100 of a portable device 102 that can implement various embodiments of a variable rate scrollbar. Portable device 102 is an example of any of the various types of portable devices described with reference to FIG. 2 and can also be implemented with any number and combination of differing components as described with reference to the example device shown in FIG. 4. Portable device 102 includes an integrated touch-screen 104 to display user interfaces, user interface elements and features, user-selectable controls, various displayable objects, and the like. Portable device 102 also includes at least a touch-screen driver 106 and a scrollbar application 108 to initiate display of a variable rate scrollbar 110 and the various user interface elements, features, and controls.

[0013] In various implementations, the portable device 102 can be utilized as a music and/or video player, for email communication, text messaging, as a photo viewer, as a portable phone for voice communication, and/or for many other applications. In this example, portable device 102 includes a display of media items 112, which may be a list of email messages, text messages, digital photos, song selections, or any other type of media items that are listed for user selection. The portable device 102 includes a memory to store groups of the media items that are grouped by a page, a day, a week, and/or a month that corresponds to a date associated with a media item. For example, email messages and text messages can be grouped by the date when an email message or text message is received. Similarly, digital photos may be grouped by the date when a photo is taken and song selections may be grouped by the date when a song is downloaded.

[0014] In an embodiment, the scrollbar application 108 initiates a display of the variable rate scrollbar 110 on the touch-screen 104 for user selection or manipulation to navigate the media items at variable rates according to the groups of the media items. A user can navigate the list, or a partial list, of the media items 112 that are displayed on the touch-screen 104. In this example, the list of media items 112 are email messages displayed in a page view of the email messages (e.g., shown as media items 1-6) that have been received on the current day (i.e., the current day is represented as a Friday in this example). The list of the email messages can be scrolled to display subsequent pages of additional email messages that are also received on the current day.

[0015] The variable rate scrollbar 110 includes an individual navigation region 114 that a user can select and/or manipulate for individual navigation of the email messages that are displayed in the list, such as in the page view for the list of the media items 112. In this example, the individual navigation region is shown as approximately fifty-percent (50%) of the variable rate scrollbar 110, although the region may be implemented as any size or percentage of the scrollbar to accommodate user selection, such as with finger or thumb touch inputs to the touch-screen 104. The variable rate scrollbar 110 can include a position indicator 116 that indicates where a user interacts with the variable rate scrollbar 110. For example, the position indicator 116 is shown displayed in the individual navigation region 114 which indicates to a user that the list of email messages is scrolled from the page group to display subsequent pages of additional email messages that are also received on the current day.

[0016] The variable rate scrollbar 110 also includes a group navigation region 118 that a user can select and/or manipulate for group navigation to initiate the display of a different group of the email messages. The variable rate scrollbar 110 includes identifiers 120 of the groups of email messages. In this example, the group navigation region 118 includes identifiers of the consecutive previous days on which email messages have been received. In this example, the current day is represented as a Friday, and the consecutive previous days are Thursday, Wednesday, Tuesday, and so on as indicated by the identifiers 120 (e.g., Th, W, Tu, M, Su, Sa for the days of the current week).

[0017] An identifier in the group navigation region 118 is selectable to initiate the display of the email messages according to the group that is identified. For example, a user can scroll from the individual navigation region 114 down into the group navigation region 118 to select an identifier 120 as shown at 122. The position indicator 116 is shown displayed at 122 to indicate a selection of the media items that are grouped by a day, such as Wednesday in this example when the W identifier is selected from the group navigation region 118 by touch input. Accordingly, a list 124 or partial list of email messages 126 that correlate to the selected group of media items is displayed (e.g., shown as Wed_Items 1-6).

[0018] When a user scrolls by touch input with a thumb or finger into the group navigation region 118, the identifiers 120 of the groups of email messages have the appearance of shifting in an opposite direction to that of the touch input. For example, as a user scrolls down through the identifiers 120 from Thursday (Th) to Wednesday (W) to Tuesday (Tu) and so on, the next consecutive identifiers are scrolled up for display at a scroll rate that increases from the scroll rate by item, to a scroll rate by day, to a scroll rate by week, and so on to a scroll rate by month. In an implementation, the identifiers 120 are shifted up at a faster rate than the drag speed of the touch input so that the user can increase the scroll rate without lifting the contact of a touch input on the touch-screen.

[0019] In an implementation, the position indicator 116 moves down along with the touch input as the user drags a finger down approximately five pixels, and the identifiers Th, W, Tu, and M shift up in the variable rate scrollbar approximately 20 pixels to display the next consecutive identifier for Sunday (S) while the position indicator 116 is positioned over the Wednesday (W) identifier. Similarly, while the user drags a finger down approximately another five pixels, the identifiers W, Tu, M, and S all shift up in the variable rate scrollbar approximately 20 more pixels to display the next consecutive identifier for Saturday (Sa), and the position indicator 116 is positioned over the Tuesday (Tu) identifier. The identifiers 120 of the groups of email messages continue to shift up as a touch input scrolls down the variable rate scrollbar to display day identifiers that correlate to different day groups of media items, week identifiers that correlate to different week groups of the media items, and/or month identifiers that correlate to different month groups of the media items. This is described further with reference to the variable rate scrollbar 110 that is shown at 134.

[0020] The touch-screen driver 106 is implemented to detect a touch input to the variable rate scrollbar 110 in the individual navigation region 114 as an individual navigation of the email messages, and also to detect a touch input in the group navigation region 118 that initiates a display of a different group of the email messages. The variable rate scrollbar 110 is implemented for individual navigation of the email messages that are displayed and grouped according to any of a page for the current day, a past day, a week, and/or a month, and is also implemented for variable, group navigation to initiate the display of a different grouping of the email messages (e.g., a different past day, a week, or a month). The scrolling rate, or how fast a user can scroll media items, is changed or varied based on how a user can select individual media items, such as in a page view, and then jump to select a group of media items. Additionally, when a group of media items is selected, a user can then individually navigate the media items that are associated with the selected group of media items.

[0021] When a user selects an identifier 120 from the group navigation region 118 to initiate the display of the email messages according to the group that is identified, such as Wednesday in this example when the W identifier is selected at 122, and the user stops scrolling or lifts contact from the touch-screen, the variable rate scrollbar 110 can be segmented into various navigation regions. In this example, the variable rate scrollbar 110 is segmented into a top group navigation region 128 for faster group scrolling to email messages that were received in recent days (e.g., Thursday and Friday); a bottom group navigation region 130 for faster group scrolling to email messages that were received on previous days (e.g., Monday and Tuesday); and an individual navigation region 132 for individual navigation of the email messages that are displayed in the list 124 of email messages 126 that correlate to the currently selected group of email messages (e.g., Wednesday).

[0022] In various embodiments, the variable rate scrollbar 110 that is shown at 134 can include day identifiers 136 that correlate to different day groups of media items, week identifiers 138 that correlate to different week groups of the media items, and/or month identifiers 140 that correlate to different month groups of the media items. As similarly described above, a user can scroll through the various group identifiers in the navigation region of the variable rate scrollbar 110 to select an identifier as shown at 142. The position indicator 116 is shown displayed at 142 to indicate a selection of the media items that are grouped by a week when the week identifier 2W is selected from the group navigation region by touch input. Accordingly, a list or partial list of media items that correlate to the selected group of media items can be displayed.

[0023] FIG. 2 illustrates an example system 200 in which various embodiments of a variable rate scrollbar can be implemented. Example system 200 includes a portable device 202 (e.g., a wired and/or wireless device) that can be any one or combination of a mobile personal computer 204, a personal digital assistant (PDA), a mobile phone 206 (e.g., cellular, VoIP, WiFi, etc.) that is implemented for data, messaging, and/or voice communications, a portable computer device 208 (e.g., a laptop computer, a laptop computer with a touch-screen, etc.), a media device 210 (e.g., a personal media player, portable media player, etc.), a gaming device, an appliance device, an electronic device, and/or any other type of portable device that can receive, display, and/or communicate data in any form of audio, video, and/or image data.

[0029] The methods may also be practiced in a distributed computing environment where functions are performed by remote processing devices that are linked through a communication network. In a distributed computing environment, computer-executable instructions may be located in both local and remote computer storage media, including memory storage devices. Further, the features described herein are platform-independent such that the techniques may be implemented on a variety of computing platforms having a variety of processors.

[0030] FIG. 3 illustrates example method(s) 300 of a variable rate scrollbar. The order in which the method is described is not intended to be construed as a limitation, and any number of the described method blocks can be combined in any order to implement the method, or an alternate method.

[0031] At block 302, groups of media items are stored that are grouped by a page, a day, a week, and/or a month that corresponds to a date associated with a media item. For example, portable device 102 includes a memory to store groups of media items that are grouped by a page, a day, a week, and/or a month that corresponds to a date associated with a media item. Email messages and text messages can be grouped by the date when an email message or text message is received. Similarly, digital photos may be grouped by the date when a photo is taken and song selections may be grouped by the date when a song is downloaded. The portable device 102 can be utilized as a music and/or video player, for email communication, text messaging, as a photo viewer, as a portable phone for voice communication, and/or for many other applications.

[0032] At block 304, a list of the media items from at least one of the groups is displayed, and the media items that are displayed are selectable from the list of the media items. For example, a list or list of media items 112 are displayed on the touch-screen 104, such as email messages displayed in a page view of the email messages that have been received on a current day. The list of the email messages can be scrolled to display subsequent pages of additional email messages that are also received on the current day, and any of the email messages can be selected by a user from the list.

[0033] At block 306, a variable rate scrollbar is displayed that can be selected to navigate the media items at variable rates according to the groups of the media items. For example, the scrollbar application 108 at portable device 102 initiates a display of the variable rate scrollbar 110 on touch-screen 104 for user selection or manipulation to navigate the media items at variable rates according to the groups of the media items. The variable rate scrollbar 110 includes an individual navigation region 114 that a user selects and/or manipulates for individual navigation and selection of the media items. The variable rate scrollbar 110 also includes a group navigation region 118 that a user selects and/or manipulates for group navigation to initiate the display of a different group of media items. The variable rate scrollbar 110 also includes identifiers of the groups of media items, such as identifiers 120 of day groups of email messages, day identifiers 136 that correlate to different day groups of media items, week identifiers 138 that correlate to different week groups of the media items, and/or month identifiers 140 that correlate to different month groups of the media items.

[0034] At block 308, an input to the variable rate scrollbar is detected to individually navigate the media items that are displayed from at least one of the groups. For example, the touch-screen driver 106 at portable device 102 detects a touch input to the variable rate scrollbar 110 in the individual navigation region 114 as an individual navigation of media items that are displayed. At block 310, the continued input to the variable rate scrollbar is detected to vary a scrolling rate of the variable rate scrollbar and initiate a display of a different group of the media items. For example, the touch-screen driver 106 also detects that the touch input is continued, or scrolled, in the group navigation region 118 that initiates a display of a different group of the media items according to an identifier of a group of the media items that is selected.

[0035] FIG. 4 illustrates various components of an example device 400 that can be implemented as any type of portable and/or computer device as described with reference to FIGS. 1 and 2 to implement embodiments of a variable rate scrollbar.
